complishing the ventilation of buildings and Its obiectsk are to provideiire-proof and storm-proof apalso for admitting light thereto.

paratus having efficient, easily adjustable and in case of iireoccurring, self-closing ventilating means, while at the same timeoffering but a minimum of obstruction to the admission of lighttherethrough.

To these ends the invention consists in the features, arrangements andcombinations hereinafter described and claimed an embodiment thereoir1as usually installed, being illusf trated in thev whichL Figure I is asectional elevation taken through the aXis of a ventilator. plan viewand horizontal section takeny on line 2 2 of Fig. I.

The reference letter a indicates the lower shell of the ventilator whichhas a circular contour at the bottom merged into an Octagonal or otherpolygonal contour at its top. The shell a is designed to befitted to andsupported upon a roof-plate er a tube leading accompanying drawing indown into the building or compartment to be ventilated. A slopingdellector b is secured to the top of the shell a, surrounding the same,as shown, and may be circular in its outer contour. A cylindrical shellc of somewhat larger diameter than the deflector b surrounds the entireapparatus, being upheld and secured to the shell a by a plurality p ofbrackets d.

e represents a polygonal upper shell, the number of sides of whichcorrespond to and are parallel .with the sides of the upper part of theshell a. The shell e is upheld by being secured at each rentrant anglethereof, carried horizontally and then downward, and fastened at itslower end to the inside of the shell a, as A gutter g is formed in theupper and outer iiange of the shell e and provided with drain holes 2. Aglass plate h, preferably of wire-inserted glass, rests upon the innerrim ofthe gutter g, and may be puttied thereto.

rain water is carried of through the gutter Fig. II is a- Thus sunlightmay enter the interior of the apartment to be ventilated, while anddrainholes before mentioned. Another gutter i is formed about the interiorand lower portion of the shell e, and provided with drain holes 3 forleading olf water which may condense upon the inner surfaces of theglass and shell. the gutter i is rounded and follows the polygonalcontour of the shell, having at each reentrant angle a small inwardlyprojecting lug y' which serves `both to separate the swingmglouvers andto keep the strutsf in propery position, as will presentl T'beexplained.

fm, m indicate swinging louvers, or doors, overlapping each other, andeach provided with a hook-shaped flange Z at its top designedto hookover the edge of the gutter z' so as to form a sup orting hinge, andfitted loosely vbetween the ugs j. are in lace, theyV prevent the hookedflanges Z o1g3 the su porting edge ofthe-glitterz', whilethe lugs y?said louvers; louvers are required as there are sides to the polygons ofthe shells a and e, and that the said louvers m when closed rest bygravity against the outer edge of the upper end of the shell a. Eachlouver m is provided with la flange Zr overlapping the adjacent-louverand meeting whenv closed an outside rib n-of, said adjacent louver..that close j ointsr are made between the closed Thus it will be seenlouvers, and when one of them is swung outwards it opens all the others.

Upright lever arms o are formed on an even number of oppositely disposedlouver iianges Z. In the drawing only two arms o are shown, but a largerventilator may require four, six or eight. A wire cord p is drawn tautbetween the said arms o, and has depending from its middle another cordwhich is carried down to some accessible fastening within the building.A fusible link r is interposed in the operating cord g.

In the operation of the device it will readily be understood that bypulling downward the cord g the louvers m are swung outward as far asmay be desired, or until they reach the position shown by dotted linesin Fig. I, thus regulating at will the area of the openin forventilation. Any desired system of pu leys or fastenings for theoperating cord may be employed. When the cord g is relleased the louversm, which are preferably quite heavy, close y gravity, so as to form acomplete housing in of the Ventilating tube.

The inner upturned edge of" Whenthe strutsy the louvers being displacedfromreep the said struts from bindingfthe It is obvious that as many Incase of fire the ventilator will close by the separation of the fusiblelink 7', thus making the device a tire retarder. It will also be noticedthat the device may be readily taken apart so as to occupy but smallspace in shipment, which is a commerical advantage much desired.

I further point out and distinctly claim as my invention- I. In aventilator, the combination with a top polygonal shell, of dependinglouvers hinged thereto and provided with overlapping flanges,substantially as set forth.

2. In a ventilator, the combination with a top polygonal shell, ofdepending louvers hinged thereto, and supporting members for said shelloverlapping said louvers, substantially as set forth.

3. In a ventilator, the combination of an upper polygonal shell, agutter formed around the interior of said shell, and depending louvershinged thereto, substantially as set forth.

4. In a ventilator, the combination of an upper polygonal shell, agutter formed around the interior of said shell, and swinging louvershaving upper flanges adapted to hook over the edge of said gutter,substantially as set forth.

5. In a ventilator, the combination with a lower shell having apolygonal top and an upper polygonal shell, of swinging louvers hingedto said upper shell and adapted to rest when closed against the upperedge of said lower shell, substantially as set forth.

6. In a ventilator, the combination with a lower shell having apolygonal top, and an upper polygonal shell having a gutter formedaround its interior, of swinging louvers having upper' flanges adaptedto hook over the edge of said gutter, and supporting members l l l l forsaid upper shell overlapping the upper flanges of said louvers,substantially as set forth.-

7. In a ventilator, the combination with a l lower shell having aaolygonal top, and an upper polygonal she having sides correspondingthereto, of swinging louvers hinged to said upper shell, and a sideflange upon each of said louvers adapted to overlap the adjacent louver,substantially as set forth.

S. In a ventilator, the combination with a lower shell having a)olygonal top, and an upper polygonal shell having sides correspondingthereto, of swinging louvers hinged to said upper shell, a side flangeupon each ol' said louvers overlapping the adjacent louver, and a rib onthe outside of each of said louvers adapted to meet the said side llangeof the adjacent louver when the ventilator is closed, substantially asset forth.

9. In a ventilator` the combination with a lower shell having apolygonal top, and an upper polygonal shell having its top closed in, ofswinging and overlapping louvers hinged to said upper shell so as torest when closed against the upper edge ol' said lower shell, uprightarms upon the tops of a. pair of said louvers which are opposite eachother, a cord connecting said arms, and an o poratiag cord dependingfrom the aforesaid cord having a fusible linli therein, substantially asset forth.

In testimony whereof I allixv my signature in the presence of twosubscribing witnesses at Cleveland, Ohio, this 4th day ol' May, 1908.
